Short stay near Nong Bua Lamphu and Suwannakhuha

I am planning a 3 day visit to my friends family living in a place called Ban Kok Tong in Isaan, Suwannakhuha district, about 100km from Udon Thani. I do not not wish to impose on them for accommodation so I was wondering if any member knew about any hotels or guesthouses etc that are within 30 mins drive of that Ban.

I have been scouring the various tourism sites, map sites and hotel sites with no real luck so far unless I want to stay an hours drive away in NongBua Lamphu.

I realise that this area is not geared up for any form of tourism but I am still hopeful...
